Be it known that I, CHARLES O. NELSON, e

. citizen Vof the United States, residing et Duluth, in the county of St. Louis and State of.

Minnesota, have invented certain new and useful improvements in Coiee-Boilers;end

` I do hereby declare the following to be a full,

clear, und exact description of the'invention, such as wiii ena-lilevothers siiiiled in the art to which itappertainsto make and use the same. My invention relates to improvements in coffee-pots; and it oorisists in providing` means for gag-ing the quantity of ooiee 1necessary to a given quantity oi weteryeud alsoY means for geging the quantity oi water within the por'.

it also consists ot' certain other novel een strnctions, Combinations, and arrangements of parts, ns will be hereinafter more fully described and claimed.

In the accompanying drawings, Figure l represents a vertioai section longitudinally of a, eoiee-pot embodying the features or my invention; and Fig, 2 represents e perspee tive of the ground-coffee cylinder, the tog and bottoni being removed and illustrated separateiy.

My invention contemplates the use of any preferred form of pot or receptacle, ne provided with any suitable cover, es 2. Pereilelspaced peripheral ribs, es 3 3, are formed about receptacle 1 in any suitebie number and are arranged et distances apart 'indieeting s ufcient space Within the reeeptocle for a predetermined quantity of weten The ribs 3 illustrated in the accompanying drawings, Fig'. 1, ere representative of greiduetions equivalent to two oups of beveregefe'nd the 2,57 {Cby $6 6),) (8,57 61037 regiresented on seid lio'ure indicate tite dismueefrom the bottom to the eifel et the stated number of cops of Water within recepteole L A knob, as 4, is provided above @over 2 end provided with e downwardly-projeotieg rod,

Rod 8 is adepte ed to extend downwardly e suitable distance and then support n plurality of downwardly extending rods, es 9 9. Rods 9 9 tney be V:formed in tegrel with or formed seperate from and secured to rod S, es desired.- v The lowerVA ends of rods 9 areprefernbly bentaintolioois, as ll0 l0, which hooks l0 are adapted to en? gage eyes as lltLin ears 1212, formed upzn; and extending upwardly from ,annular reg y 13 13.

These greduetionef Ice the same if applied to teas or other beverage requiring a given amount of material to a relative amount of water.

Among\the many advantages of my structure might be mentioned the oliviating of the necessity for measuring the coffee and water used and the provision of means for producing a beverage free from grounds. A great advantage may also be seen in the use of the covers 14 and 19, secured by annular rings, which rings are adapted to be applied to the ceffee-receptaele by means of bayonet-slots registering with lugs, whereby said covers may be readily "and easily removed, renewed, or replaced, andwvhereby I am able to produce a coffee-receptacle which maybe readily kept perfectly clean, is comparatively indestructible, Aand is incapable of cor `osion.`

Haying thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A coffee-pot, comprising in its construction a receptacle provided with annular marks of graduation for .indicating a comparative containing capacity, and means for indicating the relative amount of coffee necessary for a com uarative amount of water, substantially as described.

2. A coffee-pot, comprising in its construction areceptacle provided with annular marks of graduation formed in the body portion thereof and adapted to indicate t-he comparative containing capacity, whereby the contents of'said pot may be accurately ascertained, and means for indicating the relative amount of solid material necessary for a comparative amount of water, comprising a receptacle within said pot provided with grad- Anations, substantially as described.

3. The combination with a containing-receptacle provided with marks of graduation indicating the containing capacity thereof, of means within said receptacle for indicating thecomparative amount'of solid necessary for a relative quantity of beverage, comprising a smaller receptacle within said outer containing-receptacle, said smaller receptacle being provided with marks of graduation indicating given amounts of coffee, or other solid necessary to a relative quantity. of liquid, means for indicating the comparative relation of the graduations upon the containing and the smaller receptacles, and means for suspending said smaller receptacle within said containing-receptacle, substantially as described.

4. In a coffee or tea pot, the combination With a containing-receptacle provided with annular graduated indications of relative quantities contained, of means torindicating a-comparative amount of coffee or tea and means for exposing said coffee or tea to the free access of the contained liquid without permitting said solids being removed from the containing-receptacle with said liquid,

comprising a smaller receptacle with said con- ,n

taining-receptacle, said smaller receptacle beingsuspended within said containing-re ceptacle, and provided with removable perforated ends, and annular graduated indications of the comparative amount of tea or coffee contained, relative to the amount of liquid within said containing -recept-acle, formed in the sides thereof, substantially as described.

5. In a coffee-pot, the combination with a containing-receptacle provided with annular graduated indications of relative containing capacity, of means for indicatingr the relative amouutof coffee and for retaining the same in contact with the contained liquid but preventing its escape therewith, con'iprising a cylindrical receptacle within said containing-receptacle, a rod pivotally supporting said cylindrical receptacle free from contact with the walls of said containing-receptacle, ears upon said cylinder and adapted to re- Ceve said rod and be supported thereby, an

annular ring to which said ears .are secured,

formed with bayonet-shaped slots, a gauze covering secured beneath said ring, whereby the same is adapted "to form the cover for said cylinder, a cylindrical body portion formed with lugs on its periphery for registering with said bayonet-shaped slots and retaining said ring in position on said cylinder, another annular ring formed with similar slots, supporting a similar gauze and adapted to be secured by similar lugs on the bottom .of said cylinder, legs secured to the bottom ring and adapted to prevent contact of said bottom gauze with the bottom of said containing-receptacle, and annular rings of graduation for indicating the comparative amount ot coffee relative to the quantity of liquid in said containing-receptacle,substantially as describedA t. A coffee-pot, comprising in its construction a receptacle provided with marks of graduation for indicatinga comparative containing capacity, and means for indicating the relative amount of coffee necessary for a comparative amount of water, substantially as described.

In testimony whereof I hereunto allix my signature in presence of two witnesses.
